What are the factors that affect where organisms can live?

What are the factors that affect where organisms can live?

Some of the ​abiotic​, or nonliving, factors that affect organisms’ ability to survive include temperature, light availability, soil type, water, salinity levels, pH levels, nutrient levels, topographical features and altitude.

What are some factors that could affect the number of organisms in an ecosystem?

The number of organisms an ecosystem can support depends on the resources available and abiotic factors, such as quantity of light and water, range of temperatures, and soil composition. Given adequate biotic and abiotic resources and no disease or predators, populations (including humans) increase at rapid rates.

What are the effects of interactions among organisms in their environment?

Mutually beneficial relationships can increase the populations of both species interacting. And the organisms influence their environment, shaping Earth’s surface and the resources available to ecosystems. Thus, interactions among species are a major component of how like on Earth persists and evolves through time.

How do abiotic factors affect organisms in an ecosystem?

Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations. They help determine the types and numbers of organisms able to exist within an environment.

What is the number of organisms an ecosystem can support called?

carrying capacity
The largest population that an environment can support is called its carrying capacity.

What are the 3 main interactions among organisms?

The term “symbiosis” includes a broad range of species interactions but typically refers to three major types: mutualism, commensalism and parasitism.

What are two examples of how abiotic factors can affect an ecosystem?

An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents. Abiotic and biotic factors work together to create a unique ecosystem.

Which is catastrophic event would most likely result in trees being knocked over?

Which catastrophic event would most likely result in trees being knocked over and the disappearance of most of the plants and animals along a narrow path in a forest ecosystem? high winds can knock down tall trees, storm surges can move saltwater onto land, and soil can wash away due to high water

Why are there fewer organisms at each feeding level?

The most likely explanation for showing fewer organisms at each feeding level going up the pyramid is that Letter A in the pyramid represents… In a pine forest, there are different species of birds known as warblers that are able to coexist on the same pine trees.

Why are organisms cannot produce populations of unlimited size?

16. The reason that organisms cannot produce populations of unlimited size is that the resources of Earth are finite there is no carrying capacity on Earth species rarely compete with one another

What happens to the food web if the fish population decreases?

A food web is represented in the diagram below. If the fish population decreases, what is the most direct effect this will have on the aquatic ecosystem? The krill population will only be consumed by seagulls. The chart below shows a sequence of events that was observed at an abandoned ski center over a period of years.
